A thorough discussion of the geology of Utah, from Precambrian to Quaternary. The state of Utah is unique in having representative strata of every era, so the book from front to back is a more or less seamless journey through time. On the way Stokes gives excellent reviews of the fossils, mineral deposits, and scenery, along with the mandatory topics on sedimentary and igneous rocks. The entire state of Utah is covered region by region as well as through time, and special attention is given to the Wasatch Range faults, hot springs, and theoretical formation. Excellent photos and exact locations are provided for most of the rock layers, so you can check out the strata yourself. Highly recommended for anyone interested in geology. And, if you're not interested, this may kindle the flame.
